Method of Cleaning a Cooking Appliance and Cooking Appliance

A method of cleaning a cooking appliance comprising a cooking chamber and a heating device having a heating pipe, wherein the heating pipe has a first, actively heatable section and a second section adjacent to the first section, which is not actively heatable, wherein during normal operation of the cooking appliance, impurities deposit and burn onto a burnt-on area in the second section, wherein the method comprises the following steps:

• a) selecting a cleaning program;
• b) switching on the heating device so that the first section of the heating pipe is heated;
• c) operating the heating device over a cleaning period at a power such that a temperature is reached over a combustion period of at least 1 minute and preferably at least 5 minutes by heat transfer in the burnt-on area, so that the impurities adhering in the burnt-on area are detached, wherein at the same time it is prevented that the temperature in the cooking chamber exceeds a maximum permissible cooking chamber temperature.
